Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.266G>A (p.R89H) alteration is located in exon 2 (coding exon 2) of the TMEM151B gene. This alteration results from a G to A substitution at nucleotide position 266, causing the arginine (R) at amino acid position 89 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
